Add force flag when cleaning up generated files
Add force flag when cleaning up generated files

Under certain catastrophic failure scenarios the expected puppet
generated content may be missing from the local directory when `vagrant
destroy` is run. In this unfortunate circumstance our destroy middleware
can make actually destroying the broken image difficult by erroring when
attempting to clean up the files. Adding the :force option to the remove
commands suppresses all StandardErrors that might otherwise be thrown.
